    window: Wait before checking songs availability on launch
    
    A 'songs-available' checks happens on launch to check that the music
    library is not empty. If no music is available, an empty view is
    displayed. This relies on Tracker being already loaded. However, if
    Tracker is not yet available, the EmptyView is shown for a very short
    time and then the AlbumsView is displayed once Tracker becomes
    available.
    
    This issue is fixed by adding a timeout to ensure that Tracker is
    loaded before checking songs availability.
